You can use MSER: http://www.mathworks.com/help/vision/examples/automatically-detect-and-recognize-text-in-natural-images.html

The topic of recognizing text is known as Optical Character Recognition, often abbreviated to OCR. Any technique that can recognize text in images is an ocr technique. It is not possible to recognize text without using ocr, because anything recognizes text is defined to be ocr.

Well you can recognize text regions first using things like MSER or other methods without identifying the corresponding actual true letter that the blob represents, which can come in a later stage. In the example I linked to, the letters are first identified and the OCR part doesn't happen until "Step 5: Recognize Detected Text Using OCR".

I don't have access to the ocr() function with its specific toolbox. I've gone through the MSER example mentioned above and was able to follow along. However, at the end, it uses the ocr function, which is no good for my case. Do you have any other ideas/leads I can look into here?

You're welcome to write your own OCR algorithm. You can start here.
